I've also done high protein breakfasts, they work out well.

IF provides unique benefits, not saying it is the only way, but it is a comfortable way.

My lack of energy in the morning is more due to my internal clock being shifted about 8 hours forward. My natural hours would be to take at ~1pm and be up until ~4am.

Separate issue. :)

Have you done a sleep or diet study or are you just making assumptions based on your experience?

[dijit]

There are numerous studies into 'night owls' and such a people do exist, I was actually reading about this earlier due to the fact I've always been more active, alert and mentally capable when waking up at 11-13 as opposed to times earlier, and the energy lasted throughout the day.

I think the Wikipedia page on night-owls explains in greater detail the exacts of what is essentially a genetic predisposition, the sources hold up too.

Anecdotally, I've tried many diets, I thought I had insomnia at one point and the doctors did not disagree, taking pills does not make it easier- you feel more disconnected and my usual grumpy demenour is more apathetic.

As with most things YMMV

My guess is the Delayed Sleep Phase Syndrome ( http://en.wikipedia.org/wiki/Delayed_sleep_phase_disorder )

One problem I have with doctors is that everything is a fucking disorder if it deviates from the mean in any way. There are people who are far more functional and productive following this sleep pattern. I can't imagine going to bed at 11 and waking up at 7 every day.

A thing is called a "disorder" if

1. it makes it hard to function in society; and

2. it can be treated or mediated somehow, so there's a point to having a name for it.

Basically, a "disorder" is a node connecting "symptoms" to "treatments."
